## Analysis

THE ACFT COLLIDED WITH A SNOW BANK DURING LANDING AND NOSED DOWN. THIS WAS THE STUDENT'S FIRST SOLO LANDING. THE STUDENTTHOUGHT THE LANDING WAS ALL RIGHT EXCEPT THAT THE ACFT KEPT GOING TO THE LEFT IN SPITE OF RIGHT RUDDER. SOME POWER WAS STILL ON THE ACFT. THE INSTRUCTOR THOUGHT THE ACFT LANDED WITH THE NOSE LOW AND SKIPPED BACK INTO THE AIR. IT DEPARTED THE RWY DURING THE 2ND TOUCHDOWN. THE INSTRUCTOR SAID THE STUDENT HAD 10 HRS DUAL AND 27 LANDINGS PRIOR TO THIS FLT. THE STUDENT IS A DEAF MUTE. THE TOWER USED LIGHT SIGNALS FOR LANDING CLEARANCE.
